High current also mean increases the battery internal temperature which can probably operating beyond the battery specification charge current. I’ve read that “heating” the battery too hard could potential have done some damage to battery and life cycle.
High current cell aren’t that cheap and you don’t definitly want something tearing off your battery.
That the first case, 2nd is when the charger charge li ion cell beyond 4.20v threshold and stay there for pro long time also one of the reason of why internal battery’s temperature to rise much higher than specs and worst of all, likely to harm battery life cycle.
I’ve also been seen that 3amps charge can push cell temperature up to 40 celcius which is still ok but for me pretty darn high. Now we have 4amp, wonder how that will look like…
Because there are few countries with anything like the renewable capacity for charging large numbers of electric vehicles. The UK is already looking at electricity shortages in the future, large EV use will make that worse.
Yes, you are totally right that’s on the display.
But the display also states 100%.
But at 100% it won’t charge a 4.1A. So I wonder it’s just photoshopped for advertising reasons.
This looks like it could be nice, but it’s not actually available anywhere I order from. Hopefully it lives up to the headline without hurting the batteries. I think I may get one once they can be ordered.
FWIU .6C is commonly considered as the “safe” charging rate. For 3Ah 30Qs, for instance, that would be 3x.6 = 1.8A. What’s the tradeoff when charging at 1.3C? What rates use electric car manufacturers when fast charging? What’s the impact on the batteries?
If it is negligible or acceptable, then why not?
PS: it seems everybody is fast charging nowadays anyway.
